Chris's tiny little infant toes feel so good against your dick, you don't see any reason to make things complicated. You tell yourself that you're just gonna play a quick little game, just to see how far his toes can go. Maybe you'll even be able to fit a foot in, but it'll be fun to try none the less. No reason to take his diaper off, no reason to get your hopes up by turning this into a big event. Just a little game! You elect to leave your underwear on, just pushed down below your balls. It makes them look bigger and plumper, anyways. You continue to bounce Chris with one arm while you use the other to smear your heavy flood of precum around your shaft and head, the lewd slapping noises of adult male masturbation filling the nursery. You giggle and babble at your laughing son while you try to finger your slit a little, easily sliding one, then two of your thick fingers into your cock. Chris laughs at the silly face you make, your eyes rolling back and tongue lolling out a bit, but it feels so good to touch your cock from the inside that you can't help it. Satisfied with how much finger you stuffed into your cock, you remove them with a wet sound and unflinchingly bring that same hand to grab onto Chris. You hold him in front of you, quiet crinkle sounds coming from his diaper as his legs flail around aimlessly. "Wanna play a game, baby boy?" You ask him, giving him a few wiggles. "Let's play Tuck the Baby in! Just be a good boy and let Daddy try this out, okay?" He giggles his response, an enthusiastic yes if you had to translate from baby-babble. You give him a big smooch on his face, leaving a dribble of drool on his soft skin. You carefully lower him down so that one little foot heads straight for your gaping piss slit. You brace yourself as his foot gently kicks against your dickhead, barely suppressing a moan. It feels even better than it did before, and you're glad you're giving this nasty business a try. You lower him down more, his toes easily sliding into your slit, then his entire foot pops in with a squish. You're surprised at how easy and painless it was. You drop him down another inch, and your cock hungrily sucks down his lower calf. The tiny limb is still moving around inside of you, making you swear softly under your breath. If one foot was that easy, you wonder how two feet would work. You pop your son's foot out of your cock, leaving your dick slurping at the air. "Don't worry, I'm gonna give you something better than one foot." You promise your heavy dick. "Keep still, okay, Chris? Let Daddy do this." You say to your infant son, voice going husky. You keep him held up with one strong hand while the other wraps around his little ankles, keeping his feet as together as you can. He can't do pointed feet on command yet, but you manage to make do. You lower your slightly-restrained son back down, circling your urethra with two sets of toes. You hiss slightly as you stick them into your slit, glad that you recently cut his cubby toe nails. Your cock responds to the stimulation by throbbing bigger and harder, gaping the slit open wider than you've ever seen it. You lower Chris's feet and ankles in inch by inch, taking things nice and slow. Chris continues to babble cheerfully, tickled by the warm, wet muscles flexing against his lower limbs. He isn't bothered by the fact that he can no longer kick his feet around, but his efforts in trying make for a few near-orgasmic moments for his pleasure-hazed Daddy. You stare intently as your infant son's ankles disappear into your cockslit. You don't even consider stopping as you gently feed his calves into your dick, only pausing to take a breather when his knees are resting just outside the puffy lips. You're heaving like you just ran a marathon, precum dripping down your shaft and pooling on the floor around your feet. You think you should have started sounding years ago, but it's better late than never. You're only thinking of taking things deeper, of pleasuring yourself even more with your son's tiny body. It's amazingly easy to push Chris down even further. The sounds of drooling baby babbles and slimy cock slurping and sticky precum drips mix together into a foul, lewd soundtrack, only interrupted by the familiar crinkle of Chris's diaper. You refocus your eyes to find your baby boy is thigh deep into your dick, your eager slit pushing up against his puffy little diaper. You gape in amazement at how distended your upper cock looks, practically doubled in thickness from being filled with cub meat. All higher thinking has left you at this point, so consumed by lust and perversion. You move your hands up to your son's tiny shoulders and give him a swift push, stuffing the diaper into your cock in one fell swoop. The slightly rough diaper material scratching against the inside of your cock overloads your mind for a second, your hands coming up to grab at your hair and wipe your eyes, letting out a loud moan into the nursery. You gasp and open your eyes, finding your son being held by your massive, growing cock. His upper body sways around a little, but you're so hard that you can tell he won't be falling over. A crazed smile tugs at you lips as you balls growl loudly, the stretching feeling in your urethra only making them hungrier. Chris answers with his own cry, uncomfortable that he can't freely move his legs anymore and unhappy with the rough treatment to his shoulders. You coo at your son, trying to sooth and calm him down so you can continue with your deviant pleasures. Chris looks up at you in naive confusion, his chin wobbling. He doesn't understand why you shoved him so roughly waist-deep into your fatherly erection. His little baby hands slide around on the wet surface of your huge spongy cockhead, curious what the warm thing creeping up his body is. You lovingly cup his head in your big hands, streaking precum all over his skin as you soothe him down. You shoosh and moan in alternating stretches, getting higher and higher on pure lust as hormones and affection race in your blood. When you get too jittery to rest anymore, you resume your erotic consumption. Your dong burbs little splatters of precum up your son's tiny stomach, the supple skin disappearing into the dark depths of his Daddy. You tickle the pale fur as it gets sucked in, fingers poking into the squishy baby fat. Chris giggles, a little, but still seems mostly confused and upset. As his arms beat against your flushed plum, you realize you're about to hit a bit of an obstacle. Unless you wanted your fat dickhead to push your son's arms up at an uncomfortable angle once you reached his armpits, you were going to have to do something about the flailing limbs. "Let's get your wittle arms tucked into Daddy, baby. Then you'll be nice and snug and safe!" You coo at the infant boy as you grab hold of his slimy hands, gently feeling the little pads. You titter in pleasure as you quickly shove his arms down beside his chubby tummy, splorting them into your piss slit one right after the other. Chris protests the harsh treatment, eyes screwing up as he starts to scream and cry for real. You've become so sick on perversion that the sound only makes you harder, hips fucking upwards on auto-pilot. Your engorged shaft has grown so much that Chris's little head is only inches below your own, supported entirely by his Dad's deviant dick. You lean down and meet your son halfway, once again peppering his adorable face with sweet paternal kisses. You see little splatters of your precum and spit through half-lidded eyes, the salty nastiness on your tongue. Your kisses turn harder, more open-mouthed. You never imagined that newborn fur and adult precum could taste so good together. You start to lick long stripes up his cheek and around his nose and eyes, even drag your tongue against his his fuzzy head. A powerful gravity draws your mouth over his much smaller one, and soon you're swabbing out his toothless mouth with your thick tongue, silencing his screams. Your saliva swirls together and drips down both your bodies, your lips smacking against his. You can feel him grumble and whine against your mouth, but you keep kissing until you can't kiss anymore. You look down with a big, loving smile at your son, his crying face looking up at you, completely framed by the deep purple of your aching dong. Your fleshy dicklips pulsate and throb around his head. You stare down at him, your tongue hanging out of your mouth, masturbating your hungry cock while the slit slithers up the last inch and ever so slowly closes up around his little face. You close your eyes when he finally sinks completely into the dank insides of your cock, memorizing the image forever. Your cock burbs a fat load of precum, it's opening finally clear of baby cub. Though he's totally inside your dick, Chris still has a little ways to go down your shaft. The top half of your dick is massively distended with a squirming bulge, your son's cries hard to hear through so much thick erection meat. The cries are almost drowned out by the sick noises of his little arms and legs wiggling against the slimy surface of your urethra. You've never heard such a perverted symphony before, and every note of it makes your cock jump and throb, sucking the bulge further down the shaft. Everything is a haze of sinful pleasure, but you can feel the tired ache in your thighs from holding up all that baby and cock meat for so long. You amble over to the nursery changing table, where you quickly sweep everything to the side and hop up, letting your huge cock rest against your sweaty chest. You fall into a deep pedo-zone as your cock swallows down it's infantile meal, your squirming bundle of joy lighting your every brain cell on fire. The boy is so confused and scared, enveloped in a tight, undulating heat. Slick precum covers every inch of his skin, trickling down his throat and getting stuck up his little button nose. He sputters and coughs in the darkness, frightened by the deep growling he hears from below. After a few minutes, Chris's toes land on a tight sphincter at the base of your dick. Far too young to be able to stand, his body crumbles down and curls up as the rolling walls around him push him down against it. It's an unfamiliar muscle, and you labor trying to control it. Your hands wander down to the stuffed area, massaging yourself right where your bloated cock meets your rumbling balls. The loose sac feels hot to the touch, angry babbles emanating from your hungry testes. You don't know how you know, but you're so sure that you're seconds away from getting your little boy right into your manly nutsac. You flex and work your pelvic muscles, only serving to push your boy harder against the tight muscle. In a moment of lucidity, you remember how you always get your dick to go down during unwanted erections, and find your answer. You let yourself totally relax, falling back onto the table, your cock landing with a splat on your chest. A few moments later you gasp and shudder as you feel the sphincter loosen. A gust of hot air reeking of potent dadcum washes over Chris, his little body starting to slide into your sac. The tiny infant squirms and coughs as his little lungs are filled up with pure cum stink. The dank air inside of your sac is even warmer than tight heat of your cock tube. Chris's legs wiggle around, startled by the floor practically opening up below him. He slides into your sac wet and sticky, birthed by the sphincter into an inferno of paternal cum. You grunt at the unique feeling of your son passing through the base of your cock. You feel his toes tickle your swollen testes, then start to dip into the hot pool of cum sitting in your sac. Your sac is so sensitive that you can feel every ripple and wave in the cum as your son's legs and ass slide in. When he falls all the way in, the slimy ring of muscle finally sliding around his head, you can hear the squishy plop of his precum soaked diaper landing between your testes. You don't remember your loose sac ever being full of actual liquid cum before, but from the sloshing feeling you're getting down there you figure that has to be the case now. You miss the stretched feeling in your cock, but Chris's arms and legs sliding around the supple skin of your ball sac and bumping up against your huge, swollen testicles bring on their own surge of pleasure. The need to see what's happening outweighs your want to take a little rest and gather your strength, so you suck it up and hoist yourself back into a sitting position, eyes as wide as saucers as you look at your full sac. Amazingly, a baby-stuffed ballsac was way more obscene than a baby-stuffed cock. Your sac is huge, spilling over onto your thighs from where it sits at the edge of the changing table. Your testicles make huge lumps in the fleshy skin, but Chris makes an even bigger lump, a chubby bulge taking up most of the space in your nuts. You can see imprints of his limbs moving up and down in the skin, and the loose, goopy nutflesh leaves nothing to the imagination. Your mouth and cock drool heavily as tiny hand prints rise up in the hairy wrinkles of your scrotum, along with the occasional foot print. Rarely, a soft mask of your son's face presses up and gapes at you from the sac, mouth open wide as he wails and cries. The noises are muffled and gurgled, screamed through a mouthful of pungent semen. You gently explore the wriggling landscape with your hands, holding limbs and touching his face. It has the added benefit of rubbing your thick cum all over him, coating him in a healthy layer of white jizz. You have to see what you look like with such a fat ballsac. You ease yourself off the table, holding your Chris-sac until you're on steady feet. You tenderly drop your sac, letting off the weight bit by bit to see if it'll hurt from the weight pulling it down. It tugs a little at your groin, but it feels nice, like you're wearing a choice ball stretcher. It feels weird, but erotic, which you think is the theme for the night. You take a few test steps, you cock throbbing as the heavy weight below it sways a little between your thighs. You waddle over to your room, your nuts sloshing and gurgling and crying with every step. The starving hunger has faded, naturally, and all that's left is a deep sense of satiation. "Good baby, goooood baby." You whisper to your struggling sac. You're awed by your reflection in your full body mirror. Your upper body is the same sexy chest and core you've always remembered, but now it's underlined by a giant set of genitals. Your cock reachs over a foot long now, sticking straight up and rhythmically beating against your pecs, splattering precum. Your nuts hang down super low, the lowest point well below your wide-spread knees, still wriggling and squirming like a sack of snakes, if snakes had cute little hands and adorable muzzles. Your mirror image is turning you on something fierce, but the background of your bedroom is too boring. You grunt mindlessly as you pick up the mirror and slowly haul it over to the nursery, setting it up so you can see the empty crib and stack of stuffed animals from around your swollen gonads. The change of scenery makes it all so much better. You stand in front of the mirror, looking at yourself from every angle. Your sac gurgles and glorps as you spread your legs and stick your ass out, letting your balls dangle down as you check yourself out from behind. You spy your underwear on the floor in the mirror. It must have fallen off your ankles sometime during your incestuous sounding session. You smirk as you waddle over and pick it up, stepping into the well-worn leg holes and pulling it up to see how it fits now. The fabric is old and stretchy. Though the pouch of it is used to your regularly-sized set of hefty equipment stretching it out, you push it to it's very limit as you rest your son-sac into it. Amazingly it fits, but just barely. You can feel it almost cutting into your firm ass, the pouch completely stuffed with cock and balls. It makes you look almost more nasty than just the bare sac. When it's supported by your briefs, it's harder to tell that your ballbag is so huge because your baby boy is trapped inside. The only give is that frenzied squirming, the tell-tale impressions of hands and faces visible through the off-white fabric. You shake your hips, bouncing your bulge up and down, the thick wet sloshing noises deafening in the otherwise silent nursery. You hear Chris sputter and cough, no doubt having gotten a mouthful of cum in his yelling mouth. You wonder how much scum he's been forced to swallow by now, hoping his little tummy is distended from the sheer volume of papacum. The glorping gurgles and babbling bubbles are starting to get loud. Your sac tingles with a strange feeling, and you can't help but draw the connection to the sounds of your stomach after you eat a huge feast. Your mind races with what the two processes could have in common. Are you feeling so nasty and sick that you want it evil? Are you just so gooned out on the sloppy cum noises that you want things to get silly and messy? Or are you thinking of all the good times you've had with baby Chris, and feeling a surge of fatherly love?
